Weathering, Deposition, Erosion Conclusion

The grinding/scratching away of rock by other rock particles carried in water, ice, or wind

• Frost wedging

• Exfoliation

• Oxidation

• Abrasion

A type of chemical weathering in which a substance combines with oxygen, as when iron oxidizes, forming rust.

• Acid rain

• Oxidation

• Reaction to water

• Exfoliation

Over millions of years, the shape of mountains on Earth's surface can change to low hills and then rolling plains. These changes are most likely caused by-

• Folding and faulting

• Volcanoes and Earthquakes

• Human activity

• Weathering and Erosion

A student wanted to demonstrate weathering and erosion. The student put the same number/size of rocks into 2 tin cans, then added a small amount of water to both cans. Can A was shaken at a constant rate for 15 minutes, and can B was shaken for 60 minutes. The student then drained out all of the water and placed the rocks on the desk to observe. What is the best prediction of how how the rocks will look after this experiment?

• The rocks in can B will become larger and rounder than can A

• The rocks in can B will become smaller and rounder than can A

• The rocks in can A will become smaller and rounder than can B

• The rocks in can A will become Larger and rounder than can B

Which type of sediment does wind erosion most strongly affect?

• Loose, sandy soil

• Wet rocks

• Wet, compacted soil

• Dry, compacted soil

Which type of area is more likely to weather and erode? An area with a lot of vegetation (plants) or an area with very little? Why?

• The area with very little vegetation, because the roots won't be able to burrow through the rocks to weather it down.

• The area with a lot of vegetation, because the roots will burrow through the rocks causing a landslide.

• The area with very little vegetation, because it has not roots to absorb extra water or hold the soil together. The extra water and loose soil is likely to become a landslide/mudslide.

• The area with a lot of vegetation, because the roots will absorb any extra rain water, and will also hold the soil together preventing a landslide.

What is the difference between weathering and erosion?

• Erosion breaks down the rocks, and weathering carries the broken pieces away.

• Erosion carries broken pieces away, and weathering builds the pieces back up into another land mass.

• Weathering carries broken pieces away, and erosion builds the pieces back up into another land mass.

• Weathering breaks down rocks, and erosion carries the broken pieces away.

A student prepares a model by filling a plastic bottle with water, capping it tightly, and placing it in the freezer for 24 hours. After 24 hours, there are large cracks on the bottle's sides. The student's model most likely represents which of the following types of weathering:

• Acid rain

• Oxidation

• Frost wedging

• Abrasion

A delta is a large deposit of sediment that forms where a stream enters a large body of water. What causes this to happen?

• Erosion

• Weathering

• Deposition
